The LCMXO640E-3T100C is a MachXO family FPGA optimized for glue logic, bus bridging, power-up control and general control logic. It combines non-volatile configuration with FPGA-style lookup-table architecture, providing instant-on capability and flexible in-field reconfiguration for a wide range of commercial embedded designs.

Key device attributes include 640 logic elements, 74 I/Os, a 100-pin surface-mount LQFP/TQFP package (14×14 mm), RoHS compliance, and a commercial operating temperature range of 0 °C to 85 °C. The device operates from a supply rail in the 1.14 V to 1.26 V range.

Key Features

• Non-volatile, instant-on operation  Single-chip non-volatile configuration enables power-up in microseconds without external configuration memory, improving system startup time and security.
• Reconfigurable logic  640 logic elements provide flexible implementation of glue logic, bus interfacing and control functions, with support for in-field reconfiguration.
• Flexible I/O  74 programmable I/Os in the 100-pin package accommodate a variety of interface needs commonly required in embedded designs.
• Family-level memory and IP support  MachXO family architecture includes distributed memory and system-level features (refer to family datasheet for available memory and IP blocks).
• Power and sleep management  Family features such as sleep mode provide substantial static current reduction for lower-power standby operation.
• Package and mounting  Available in a 100-LQFP surface-mount package (100-TQFP, 14×14 mm) for straightforward PCB assembly and prototyping.
• Commercial grade and environmental  Commercial operating grade (0 °C to 85 °C) and RoHS-compliant packaging for regulatory alignment.

Typical Applications

• Glue Logic and Board-Level Control  Implement address decoding, bus steering and simple state machines to consolidate discrete logic and reduce BOM.
• Bus Bridging and Interfacing  Serve as a configurable bridge between different bus standards or voltage domains using the device's programmable I/Os.
• Power-Up and Reset Control  Provide reliable power sequencing and system initialization with instant-on configuration and single-chip non-volatile storage.
• General System Control  Replace multiple PLDs or discrete logic with a compact FPGA implementation for user interfaces, monitoring and control tasks.

Unique Advantages

• Single-chip non-volatile configuration:  Eliminates the need for external configuration memory, simplifying BOM and board layout.
• Fast power-up:  Instant-on behavior allows systems to come online in microseconds, improving responsiveness for embedded applications.
• Compact, industry-standard package:  100-LQFP/TQFP (14×14 mm) provides a small footprint with 74 I/Os for dense connectivity on space-constrained PCBs.
• Commercial temperature and RoHS compliance:  Clear environmental and regulatory alignment for mainstream commercial products.
• Design tool support (family):  The MachXO family is supported by ispLEVER design tools to assist with synthesis, placement and timing for efficient implementation.
• Field reconfiguration capability:  Family-level features support in-field updates and background programming to evolve logic without full system downtime.
